Drill Guide Pin Suggestion for Kreg

I have a K4, and I find it really hard to access the drill pin guide (the thumbscrew that locks the jig's proper height setting) when the vacuum attachment is in place. It seems that adding a phillips or square drive to the end of the drill pin guide would make it easier to turn.

Since we are "improving" Kreg's designs, I find it difficult to place the drill guide into the base, since it appears to be a slight interference fit. Once it's started, it slides easily, but by just touching both sides of the base to my grinder, I added a chamfer on both sides and facilitated insertion of the drill guide.
